Hey guys, replaced my plugs today after around 10-15 Hours of use and plugs came out white. Not chalky white but machine seems to be running Leanne the looks of all 3 plugs. Running great but lean. Of course I would to have it running a little more on the rich side. Are there any adjustments to richen it a tad? Thanks ahead of time, you guys are great. Oil level is good and has always been maintained with a recent "Jerry" SC Rebuild. Ty.
